'NIPENSATING JOURNAL-BEARING.

SPECIFICATION forming part of Lettersvllatent No. 763,077, dated June21, 1904.

Application filed March 2l, 1904.

To @ZZ whom it may concern:

Be it known that I, MAX F. STADTMULLER, a citizen of the United- States,residing at Pomeroy, in the county of Calhoun and State of Iowa,haveinvented certain new and useful Improvements in CompensatingJournal-Bearings, of which the following is a specification.

In the operation `of machinery, such as cream-separators, considerablevibration is occasioned.

This invention provides a bearing for neutralizing in whole or part thevibration, thereby obviating the noise, the wear and tear, and themanyobjectionable features attributable thereto.

The invention consists of a box, frame, or

and yielding braces between the box and bearing for centralizing thelatter and taking up the vibration, said braces unitedly constitutingacompensator, the tension of which is regulable to offer agreater orless resistance to the amplitude of vibrations. y

' The invention further consists of a tensionregulator for the saidcompensator and interlocking means between said regulator andcompensator to prevent relative turning when adjusting the parts to varythe tension of the yielding braces.

The invention also consists of the peculiar formation of the yieldingbraces, the mounting therefor, and an expansible ring passed through theeyes or coils of said braces and holding them in line and admitting oftheir inward and outward movement, sol as to snugly fit the boX or frameforming a support for the bearing as a whole.

The inventionfn'rther consists of the novel features, details ofconstruction, and combinations of parts, which hereinafter will be moreparticularly set forth, illustrated, and finally claimed.

In the accompanying drawings, forming a part ofthe specification, Figurel is a side view of a journal-bearing embodying the invention, showingthe same in connection with a separator, the lower portion of which isillustrated in section. Fig. 2 is a perspective view of the compensator.Fig. 3 is a Vertical central section of the component parts of thebearing, the same senti No. 199,182. ci@ modem being on a larger scale.Fig. 4 is a perspective view of the expansible ring upon which theyielding braces are mounted, one (being lin position thereon. vView of ayielding brace. spective view of the tension-regulator.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters. y .Y

` The compensating journal-bearing is` designed for general applicationwhere vibration of a rotary shaft is to be utilized, and inasmuch as itis peculiarly adapted for separators and analogous machinery it isilluswhich the tension of the yielding braces comprising the compensatoris regulated. The

rotaryA shaft 3 is snugly j ournaled in the sleeve 5,*so as to preventany lost movement bentween them. The term sleeve as applied to the part5 embraces any element that may be used in the capacity of a bearing forthe shaft 3,

The compensator is composed -of a series of yielding braces having theforml substantially as shown in Fig. 5 and disposed in a circle, so asto embrace the sleeve 5 and come b etween'itand the box, frame, or likeIsupport receiving the journalbearing as a whole. The yielding bracescomprise angularly-disposed arms 7 and 8 and one or more coils 9, theseveral parts being integrally formed and constituting portions of alength of wire bent upon itself intermediate of its ends to form Figi isa perspective' Fig. 6 is a per- IOO the coils and having its endportions extended to provide the arms 7 and 8. When the yielding bracesare assembled, the arms 7 are arranged about parallel with the axis ofthe journal-bearing, whereas the arms 8 are inclined so as to exert alateral pressure upon the sleeve 5. A ring 10 is provided to connect theyielding braces in series, and said braces have their arms 7 jointedthereto in any substantial and rigid manner. The coils or eyes 9unitedly form a circle and lie side by side, as indicated most clearlyin Fig. 2, said circle of coils being spaced from the supportingring 10.An expansible ring 11 is passed through the coils or eyes 9 and servesto maintain the same in line or proper position and to admit of thecoils moving inward or outward to allow for slight variations in thediameter of the recess 3a of the box or support designed to receive thebearing. This expansible ring may, it' desired, serve to supplement theaction of the yielding braces, particularly so if made of stoutmaterial.

The tension-regulator consists, essentially, of a sleeve 12, having aconical end 13, which is adapted to be forced between the compensatorand the bearing 5, so as to increase the tension oi' the compensator asmay be desired. The sleeve 12 snugly tits the sleeve or bearing 5, andits conical end is provided with a series of grooves 14, forming seatsto receive the inclined arms 8 of the yielding braces or compensatorelements. In this manner is provided a positive interlocking connectionbetween the tension-regulator and compensator to prevent relativeturning of the parts when the set-nut A is turned either to advance orpermit the withdrawal of the regulator, according as the tension of thecompensator is to be increased or diminished. Moreover, the seats orgrooves 14 receiving the arms 8 hold the latter in iixed position, whichis essential to the eiciency of the invention. A series of depressions15 are formed in the lower or outer end of the tension-regulator and areadapted Y to coperate with a springactuated stop 16, carried by theset-nut, so as to hold the latter in the adjusted position against anypossible casual displacement.

The compensating journal may be used in any connection where it isrequired to take up the vibration of a rotary shaft, and in thearrangement of the parts it is of the utmost importance that the shaftreceive a snug lit inthe bearing or sleeve 5 and that thetension-regulator closely encircle said bearing,

while the compensator is snugly received in the box, frame, or support,provision being had for a limited play between the tensionregulator andsaid box, frame, or support. When the tension-regulator 12 is advancedby means of the set-nut A, the inclined arms 8 are repressed-that is,moved outward by means of the conical end 13 wedging between said'armsand the sleeve -thereby oiering a greater resistance to the vibration ofthe shaft and sleeve 5, according as may be desired to meet theexigencies of the'case.

Having thus described the invention, what is claimed as new is- 1. In acompensating journal-bearing, the combination of a bearing-sleeve, aseries of yielding braces arranged about said sleeve and havinginwardly-extended arms, a tensionregulator mounted upon thebearing-sleeve andpositively interlocking with said arms of the yieldingbraces, a set-nut threaded upon the bearing-sleeve for advancing thetensionregulator, and interlocking means between said set-nut andtension-regulator to prevent casual displacement or loosening of thesetnut, substantially as setforth.

2. In a compensating journal-bearing, the

-combination oi' a-bearing-sleeve, a series of yielding braces arrangedto encircle the bearing-sleeve, means for varying the tension of saidyieldlng braces, and an expansible rlng having loose connection with theyieldingy braces and adapted to hold them in line and to admit of theirinward and outward movement, substantially as specified.

3. In a compensating journal-bearing, the combination of abearing-sleeve, yielding braces arranged in a circle about thebearingsleeve, each comprising an eye and angularlydisposed arms, anexpansible ring passed through the eyes of the yielding braces, and atension-regulator mounted upon the bearing-sleeve and adapted to beadvanced thereon so as to compress the yielding braces, substantially asand for the purpose speciied.

4. In a compensating journal-bearing, the combination of abearing-sleeve, a series of yielding braces arranged in a circle aboutthe bearing-sleeve, each comprising angularlydisposed arms and a numberof coils, the several coils of the yielding braces coming together, aring having said yielding braces connected thereto by one of their arms,and a tension-regulator mounted upon the bearingsleeve and adapted to beadvanced thereon so as to vary the tension of said yielding braces,

`substantially as specified.

and adapted to be advanced thereon so as to vary the tension of saidyielding braces, and an expansible ring passed through the series ofcoils of the said yielding braces, substantially as set forth.
